cooKs'rovnI Application filed December 9, 1926..

This invention relates generally to Cooking stoves and more particularlyto a means for mounting the oven door.

The object of the invcntion is to provide a simple Vhinge constructionof the concealed type, for mounting a stove door on the frame of astove.

Another object is to provide such a hinge construction, having` meansfor counterbalancing the weight of the door in certain postions thereofand which is furthermore operative to hold the door in proper operativerelation to 'the frame in all positions of the door.

Other objects and advantages will become apparent from the followingdescription and in the accompanying drawings, in which:

Figure 1 is a view taken from the inside of the oven section'of a stoveand showing the doors in closed position.

Fig. 2 is a fragmentary Vertical section approximately in the plane ofline 2-2 of Fig.

'1 showing one of the doors in open position.

plane of line 3 3 of Fig. 1.

In attaining the objects of this invention, the door or doors aremounted upon the front frame of the oven section, through the me- F ig.3 is a horizontal section taken in the dium of lever arms rigid with thedoor-and engaging with the frame so that it acts as a fulcrum upon whichthe door is adapted to pivot, the door being held on said fulcrumpartially by means of its own weight and partially by means of a forceeXerted thereon by a resilient member.

Herein I have shown for purposes of illustration the oven section of agas range, providing an upper or baking oven and a lower or broilingoven. This oven section is formed largely of sheet metal and comprises apair of side walls 5, a top wall 6 and a bottom wall 7. A front frame,preferably of cast metal, has top, bottom and side members 8, 9 and 10and an intermediate transverse bar 11 constituting the lower member forthefront frame of the upper or baking oven, and the upper member for thefront frame of the lower or broiling 'compartment Each of the openingsso formed is adapted to be covered and closed by means of the doors 12and 13, and suitable bottom plates 14 and 15 are provided for each oven,in the usual way.

The doors may be constructed in any preferred manner. In the presentinstance each door comprises a frame 16 arranged to abut the front ovenframe, and having a filler plate sami Na, 153,497.l

or panel secured therein in any suitable mauner. A handle 17 of usualconstruction he secured on the door frame. v

The preferred means by. which the doors are pivotally mounted uponflthestove comprises a pair of bcnt arms or levers 18 rigidly secured nearopposite endsof the lower side of the door frame in any preferred manneras by being cast integral with the frame 16.V The 4 under side edge ofeach lever is provided with rece/,ss 19 which is adapted to rest on arounded surface formed upon the Vupper edge of theflowcr frame member 9or on the intermediate transverse bar 11 as a fulcrum. The lever is soarranged on the door as to extend inwardly horizontally of the stove inthe closed position of the door, and to extend upwardly along the sidemember of the front frame when the door is in its open position. Topermit swinging movement of the arms 18 unrestricted by the bottompl'ates 14 and 15, slots 20 are provided therein; and suitablev stopmeans such as a lug 21 upon the free end of the levers 18 is sopositioned as to engage sides 10 of the front frame when the door hasbeen swung open. Thus I have provided a mounting` for the door which isadapted to rest upon the edge of the front frame as a fulcrum withoutpositiveconnection therethe case of each door a resilient member, suchas a helical spring anchored at one end in one of a vseries ofperforations in a plate 23 mounted in the central lowerfpart of the ovensection as by being secured upon the inner side of the lower front framemember 9.v The other end ofthe spring is connected to a flexible membersuch as a chain 24 which passes around a guide pulley 25 mounted on theini ner side of the front frame at a point beneathV one of thesupporting levers 18 to which the other end of said chain is attached.The connections for the two doors, as shown, extend from the anchoringplate 23 in opposite dire-ctions. It will be seen that When a door is inits closedpostiontheeffectivepullofthespring upon the door ,is at itsmaximum since the moment arm of the lever 18 is at this time thegreatest. VVhen the door is swung down- Wardly into open position, theWeight of the door acts against a decreasing efective pull by the springuntil the door reaches its open position When the inner end of the leverarm approaches its dead center position.

Thus the door is firmly held in closed position, While thecounterbalancing effect of the spring diminishes, as the door moves intoits open position, so as to be ineifective to lift the door from suchposition. However, the spring a cts in all positions of the door to holdthe lever arms 18 seated upon the frame of the oven section.

It will be observed that the construction employed is very simple andhence capable of being cheaply manufactured. lAt the same time, view inthe closed position of the doors.

I claim as my invention:

A cool; stove comprising, in combination, an oven section having top,side and rear Walls and having partitions therein providing upper andlower oven compartments, said parthe hinges are entirely concealed fromtitions forming the bottom of the respective compartments and the lowerpartition being spaced substantially above the loWer edges of the sideand rear Walls, a front frame providing openings for said compartments,doors for said openings having` lever arms rigid thereivith andfulcrumed on said frame, said partitions having slots therein to receivesaid lever arms, a plateV secured Within the loWer edge of said frontframe beneath the loWelr partition, and spring means for said doorsacting to counterbalance them and to hold them in operative relation tothe frame, said spring means comprising two springs bothV anchored tosaid plate, fiexible connections between the respective Springs andhinge members of the upper and lower doors at opposite sides thereof,and guide sheaves for said connections mounted on said frame at oppositeends thereof beneath said lower partition.

In testimony Whereof, I have hereunto af fixed my signature.
